CROSS-REFERENCE TO RELATED APPLICATION

This application is based upon and claims the benefit of priority under35 USC 119 from Japanese Patent Application No. 2015-075710 filed onApr. 2, 2015, the entire disclosure of which, including the description,claims, drawings and abstract, is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a film transfer tool that transfers atransfer layer of a transfer tape on to a transfer receiving surface anda head unit for use on this film transfer tool.

2. Description of the Related Art

Film transfer tools have conventionally been provided for application totransferring a correction tape or a tape glue. For example, JapaneseUnexamined Patent Application No. 2000-37991 (JP-A-2000-37991) disclosesa film transfer tool that includes a spatulate transfer portion and aroller that is provided on an upstream side of the transfer portion. Inthis film transfer tool, a transfer tape is fed by the upstream roller,and therefore, a light transfer operation can be provided. In addition,Japanese Unexamined Patent Application No. 10-236081 (JP-A-10-236081)discloses a film transfer tool that includes similarly a spatulatetransfer portion and a roller that is disposed on an upstream side ofthe transfer portion. A collar portion having a circular shape when seenfrom a side thereof is formed at each end of the roller of the filmtransfer tool. A transfer tape is fed to the transfer portion whilebeing guided by the collar portions along their side edges.

In the film transfer tool disclosed in JP-A-2000-37991, the transfertape is brought into abutment with a transfer receiving surface by notonly the spatulate transfer portion but also the roller providedupstream of the transfer portion, and therefore, there may occur a casewhere the roller completes the transfer of the transfer film on to thetransfer film receiving surface before the spatulate transfer portiontransfers the same. As this occurs, the transfer tape is sometimestransferred on to an unintended location on the transfer receivingsurface. Further, the transfer tape is pressed by both the roller andthe transfer portion, and therefore, the pressing force exerted by auser is not sometimes exerted on the transfer portion sufficientlyduring a transfer operation. This causes a transfer failure.Furthermore, an excessive tension is produced in the transfer tapebetween the transfer portion and the roller, leading to concerns that atraveling failure such as snaking is caused in the film transfer tool.

In the film transfer tool disclosed in JP-A-236081, the transfer tape isfed to the transfer portion while being positioned between the collarportions having the circular shape when seen from the side thereof thatare provided at both the end portions of the roller. The collar portionsare in contact with the transfer receiving surface, whereby the rollerrotates. Thus, the roller is spaced apart from the transfer receivingsurface, and therefore, the roller is never involved in transferring thetransfer tape on to the transfer receiving surface. However, thetransfer tape is in contact with the roller over a full width thereof.In this case, a difference in speed is caused between an outercircumference of the collar portion and an outer circumference of theroller while the film transfer tool is traveling. This speed differenceprevents the feeding speed of the transfer tape from being synchronizedwith the rotation speed of the roller, sometimes resulting in a casewhere an excessive tension is produced in the transfer tape between thetransfer tape and the roller. Then, there are caused fears that thetransfer operation of the film transfer tool becomes heavy, the transfertape is dislocated from the spatulate transfer portion, and a travelingfailure such as snaking of the film transfer tool is caused.

SUMMARY OF THE INVENTION

An object of the invention is to provide a film transfer tool head unitthat can enhance the capability of traveling straight when a filmtransfer tool is caused to travel and a film transfer tool that includesthis head unit.

According to an aspect of the invention, there is provided a filmtransfer tool head unit that has a head main body, a head support memberthat supports the head main body, and a transfer projecting portion thatis provided on the head main body so as to be brought into abutment witha rear surface of a transfer tape to thereby transfer a transfer layerof the transfer tape on to a transfer receiving surface. The head mainbody has side rollers rotatable back and forth that are positionedindividually at two locations lying outwards of both side edges of thetransfer tape while being in contact with the transfer receivingsurface. Support shafts that support the side rollers rotatably aredisposed so as to be spaced apart from the transfer tape.

The head main body is supported on the head support member so as torotate back and forth.

A rotational center about which the head main body rotates back andforth is positioned closer to the transfer projecting portion than amiddle point in a front-to-rear direction between a contact point of thetransfer projecting portion with the transfer tape and a rotationalcenter of the side rollers.

The head main body includes a tape feeding member that is supported soas to rotate back and forth. The tape feeding member has a drive shaftthat is rotated by means of a rotating force of the side rollers and anannular protuberant portion that is provided on the drive shaft so as tobe brought into abutment with the rear surface of the transfer tape. Anoutside diameter of the side rollers coincides with an outside diameterof the protuberant portion.

The drive shaft of the tape feeding member is supported on the head mainbody so that an axis thereof is inclined at an angle α relative to thetransfer receiving surface.

The protuberant portion of the tape feeding member has a truncated coneshape whose open angle relative to the axis of the drive shaft is theangle α, and the tape feeding member is provided so that an uppersurface side of the truncated cone shape is positioned lower on theinclined drive shaft.

The side rollers are made up of a drive member that is fixed to thedrive shaft and a side guide member that is supported rotatably by aside guide member support shaft that is provided on the head main body.

A film transfer tool according to another aspect of the invention has acase main body and a head unit that is provided at a distal end of thecase main body. The head unit has a head main body, a head supportmember that supports the head main body so as to rotate back and forth,and a transfer projecting portion that is provided on the head main bodyso as to be brought into abutment with a rear surface of a transfer tapeto thereby transfer a transfer layer of the transfer tape on to atransfer receiving surface. The head main body includes side rollersrotatable back and forth that are positioned individually at twolocations lying outwards of both side edges of the transfer tape.

In case the film transfer tool head unit according to the aspect of theinvention is applied to a film transfer tool, the transfer layer of thetransfer tape can be transferred on to a transfer receiving surface inan ensured fashion by the transfer projecting portion while realizingthe capability of traveling straight by the side rollers that areprovided outwards of both the side edges of the transfer tape. Then, thesupport shaft that supports the side rollers rotatably is provided so asto be spaced apart from the transfer tape, and therefore, there is nosuch situation that an excessive tension is exerted on the transfer tapethat lies between the transfer projecting portion and the side rollersand between the transfer projecting portion and the support shaft of theside rollers. Consequently, the occurrence of a traveling failure suchas snaking of the transfer tape is reduced by providing the head unit onthe film transfer tool.

The head main body is supported on the head support member so as torotate back and forth. By adopting this configuration, even though themain body of the film transfer tool that is connected to the headsupport member is at any angle of various angles relative to thetransfer receiving surface, the film transfer tool can perform thetransfer operation.

The head main body is formed so that the rotation center thereof ispositioned closer to the transfer projecting portion than the rotationalcenter of the side rollers in relation to a front-to-rear direction. Byadopting this configuration, even though the main body of the filmtransfer tool that is connected to the head support member is at anyangle of various angles relative to the transfer receiving surface, muchof the pressing force with which the user presses the film transfer toolagainst the transfer receiving surface is exerted on the transferprojection portion at all times. Consequently, even though the main bodyof the film transfer tool that is connected to the head support memberis at any angle of various angles relative to the transfer receivingsurface, the film transfer tool can perform the transfer operation in anensured fashion.

The tape feeding member that rotates back and forth is provided on thehead main body. The protuberant portion that is brought into abutmentwith the rear surface of the transfer tape is provided on the tapefeeding member. Then, this tape feeding member is rotated by means ofthe rotational force of the side rollers. Consequently, the head unitcan be given the construction in which the transfer tape is fed withoutbringing the protuberant portion into abutment with the transferreceiving surface. Further, since the outside diameter of the siderollers coincides with the outside diameter of the protuberant portion,the feeding speed of the transfer tape can be synchronized with therotational speed of the protuberant portion. Consequently, since noexcessive tension is exerted on the transfer tape even between theprotuberant portion and the transfer projecting portion, the protuberantportion can assist in feeding the transfer tape. Thus, the film transfertool can realize a light transfer operation.

The drive shaft of the tape feeding member is inclined at the angle αrelative to the transfer receiving surface. By adopting thisconfiguration, even though one of the side rollers is disposed on thedrive shaft, it is possible to form easily the construction in which theprotuberant portion is disposed so as to be spaced apart from thetransfer receiving surface.

The protuberant portion has the truncated cone shape whose upper surfaceside is inclined downwards, and the open angle thereof is set to theangle α. By adopting this configuration, even though the drive shaft isprovided so that the axis thereof is inclined at the angle α, theprotuberant portion can be brought into abutment with the transfer tapeso as to be parallel to the transfer tape. Consequently, since theprotuberant portion can be brought into abutment with the transfer tapein an ensured fashion, the film transfer tool can realize a lightertransfer operation.

The side rollers are made up of the drive member that is provided on thedrive shaft and the side guide member that is supported rotatably on thehead main body. By adopting this configuration, the protuberant portioncan be rotated by means of the rotational force of the drive member.Thus, the side rollers can be formed by the simple configuration.

The film transfer tool includes the head unit that includes the headmain body having the side rollers. Then, the case main body of the filmtransfer tool can rotate freely relative to the head main body.Consequently, the transfer operation can be performed even though thecase main body is inclined at any angle of the various angles. Thus, itis possible to provide the film transfer tool that holds the capabilityof traveling straight in a more stable fashion that is provided by theside rollers and facilitates the transfer operation further.

DETAILED DESCRIPTION

An embodiment of the invention will be described based on the drawings.FIG. 1 is a perspective view of a film transfer tool 10. The filmtransfer tool 10 has a case main body 5 indicated by chain double-dashedlines. A head unit support member 20 is provided at a distal end of thecase main body 5. A head unit 30 is provided at a distal end of the headunit support member 20. A transfer operation of a transfer tape T by thefilm transfer tool 10 is performed by holding the case main body 5 andpulling back the case main body 5 while pressing the head unit 30against a transfer receiving surface. Here, in the followingdescription, in a transfer operation, a direction in which the filmtransfer tool 10 is pulled will be referred to as a rear, and adirection opposite thereto will be referred to as a front of the filmtransfer tool 10. Additionally, a left and right sides of the filmtransfer tool 10 that result when the film transfer tool 10 is seenstraight ahead from the rear thereof will be referred to a left andright sides of the film transfer tool 10, respectively. Then, in FIG. 1,upper and lower sides will be referred to as upper and lower sides ofthe film transfer tool 10.

The film transfer tool 10 is used to distribute a correction tape or aglue tape. Although not shown, internal structures such as a supplybobbin, a take-up bobbin, a gear mechanism and a clutch mechanism areinstalled in an interior of the case main body 5. An unused transfertape T is wound around the supply bobbin and is then supplied from thesupply bobbin. The used transfer tape T, from which a transfer layer hasbeen transferred, is taken up by the take-up bobbin. The gear mechanismconnects the supply bobbin and the take-up bobbin so that the bobbinsrotate in an interlocked fashion. The clutch mechanism corrects adifference in rotation speed between the supply bobbin and the take-upbobbin.

Then, the head unit 30 includes a head main body 31 and a head supportmember 32 that supports the head main body 31 so as to rotate freelyback and forth. A plate-shaped support base portion 32 a is formed at aproximal end portion of the head support member 32. A locking hole 32 a1 is provided substantially in a center of the support base portion 32a. A locking shaft 20 a of the head unit support member 20 is locked inthe locking hole 32 a 1. In this way, the head unit 30 is supported onthe head unit support member 20.

In performing a transfer operation, firstly, an unused portion of thetransfer tape T is fed out from a lower side of an opening portion 6 ata distal end portion of the case main body 5 and passes a lower side ofthe head unit 30, and a transfer is effected on to a transfer receivingsurface on a lower surface of the head main body 31. Thereafter, theused portion of the transfer tape T from which the transfer has beeneffected passes the head main body 31 and an upper side of the headsupport member 32 to enter again the interior of the case main body 5from the opening portion 6 and is then taken up by the take-up bobbin soas to be wound therearound.

FIG. 2 is a perspective view of the head unit 30 that results when thehead unit 30 is seen from therebelow. FIG. 3 is an exploded perspectiveview of the head unit 30 that results when the head unit 30 is seen fromthe left and therebelow. FIG. 4 is an exploded perspective view of thehead unit 30 that results when the head unit 30 is seen from the rightand therebelow. As shown in FIGS. 2 to 4, support side plates 32 b, 32 care formed so as to extend to the front from left and right ends of thesupport base portion 32 a at the proximal end portion of the headsupport member 32. When seen sideways, the support side plates 32 b, 32c are formed so as to be tapered towards front ends thereof.

Rotational support holes 32 b 1, 32 c 1 are provided at distal endportions of the support side plates 32 b, 32 c where the support sideplates 32 b, 32 c are tapered, respectively. Left and right headrotational shafts 31 a, 31 b of the head main body 31 are supportedrotatably in the rotational support holes 32 b 1, 32 c 1, respectively.Rotational shaft bearing portions 82 b, 82 c, which are arc-shaped holeswhen seen sideways, are formed at a front side of the rotational supportholes 32 b 1, 32 c 1, respectively, and rotation restricting portions 82b, 82 c, which are sector holes when seen sideways, are formed at a rearside of the rotational support holes 32 b 1, 32 c 1, respectively, whenseen sideways. Recess portions 32 b 2, 32 c 2 are formed at distal endportions of inner surfaces of the left and right support side plates 32b, 32 c, respectively. The recess portions 32 b 2, 32 c 2 have shapesthat match shapes of left and right side surfaces of the head main body31, respectively, so that the head main body 31 is rotated smoothly.

The head main body 31 is disposed between the inner surfaces of thesupport side plates 32 b, 32 c of the head support member 32. An uppersurface of the head main body 31 is formed into a curved surface 31 cthat projects convexly when seen sideways. Plate-shaped guideprojections 31 d, 31 e are formed to extend to the front from both endsof the curved surface 31 c in its width direction. Upper surfaces of theguide projections 31 d, 31 e are formed into a curved surface thatprojects convexly when seen sideways. Inner surfaces of the guideprojections 31 d, 31 e are positioned near side edges of the transfertape T. Consequently, the used portion of the transfer tape T is guidedby the guide projections 31 d, 31 e.

As shown in FIG. 1, an opening hole portion 31 f is provided at the rearof the upper surface of the head main body 31 so as to be openeddownwards from the upper surface. This opening hole portion 31 f has alaterally elongated rectangular shape when seen from thereabove. Theopening hole portion 31 f is configured so that when the film transfertool 10 is in use, the position of an unused portion of the transfertape T can be seen from the opening hole portion 31 f through the usedportion of the transfer tape T, which enables a user to confirm that theunused portion of the transfer tape T is being fed so that a transfer iseffected on a desired location on a transfer receiving surface S.

As shown in FIGS. 2 to 4, a transfer projecting portion 31 g is providedon the lower surface of the head main body 31, and this transferprojecting portion 31 g has a substantially triangular shape when seensideways. The transfer projecting portion 31 g is brought into abutmentwith a rear surface of the transfer tape T to thereby transfer atransfer layer of the transfer tape T on to the transfer receivingsurface. The transfer projecting portion 31 g is formed so as to extendlong in a width direction of the head main body 31 while projectingdownwards. A lower end portion of the transfer projecting portion 31 gconstitutes an apex of the substantially triangular shape thereof whenseen sideways and is chamfered to be rounded. This lower end portion isformed close to the front of the head main body 31. In other words, asshown in FIG. 6, a rear surface of the transfer projecting portion 31 gis formed into an inclined surface 31 g 1, and this inclined surface 31g 1 is inclined at an angle that falls in a range of acute anglesrelative to the transfer receiving surface S when seen sideways. Inperforming a transfer operation, this configuration allows a pressingforce to be exerted gradually on the transfer tape T, whereby theoccurrence of a transfer failure such as a partial loss of the transferlayer is reduced.

Further, a front surface 31 g 2 of the transfer projecting portion 31 gis formed so as to extend upwards almost perpendicularly from a lowerend portion of the transfer projecting portion 31 g that is curvedconvexly when seen sideways. As shown in FIGS. 2 to 4, the front surface31 g 2 and the curved surface 31 c are formed continuously. This enablesthe used portion of the transfer tape T to be fed upwards smoothly.

A support portion 31 h is provided at the rear of the transferprojecting portion 31 g in a position that lies closer to a left endthereof, and this support portion 31 h supports a tape feeding member 33rotatably. The support portion 31 h includes a main shaft supportportion 60 that supports a main shaft 33 a 1 of the tape feeding member33 rotatably and an end portion shaft support portion 70 that supportsan end portion shaft 33 a 2 of the tape feeding member 33 rotatably.

An opening portion 61 is formed on a lower side of the main shaftsupport portion 60 so as to be opened downwards. An upper main shaftbearing portion 62 is formed on an upper side of the main shaft supportportion 60. The upper main shaft bearing portion 62 is formed into anarc-like shape when seen sideways that matches an external shape of themain shaft 33 a 1. Lower main shaft bearing portions 63, 64 are formedon the opening portion 61 so as to project to face each other in afront-to-rear direction. The lower main shaft bearing portions 63, 64are provided at a right end side of the opening portion 61 (refer toFIG. 2). A distance between the lower main shaft bearing portions 63, 64is formed smaller than an outside diameter of the main shaft 33 a 1.Consequently, in assembling the tape feeding member 33 to the head mainbody 31, the main shaft 33 a 1 is inserted between the lower main shaftbearing portions 63, 64 through press fitting. And, the main shaft 33 a1 is supported rotatably by an upper surface of distal end portions ofthe lower main shaft bearing portions 63, 64 and the upper main shaftbearing portion 62. Then, as shown in FIG. 5 that is a partiallyvertical sectional perspective view of the head unit 30, surfaces of theupper main shaft bearing portion 62 and the lower main shaft bearingportions 63, 64 that bear the main shaft 33 a 1 are formed to slope downto the left so as to support the main shaft 33 a 1 in an inclinedfashion.

Additionally, as shown in FIG. 5, an upper surface of the end portionshaft support portion 70 is formed into a concavely curved end portionshaft bearing portion 71 so as to support a lower side of the endportion shaft 33 a 2. The upper surface of the end portion shaft supportportion 70 is formed to slope down to the left so as to support the endportion shaft 33 a 2 in an inclined fashion.

A partition wall 31 j is formed on a right-hand side of the end portionshaft support portion 70. As shown in FIGS. 3 and 4, too, a side guidemember support shaft 31 k is erected to extend towards the right from aright side surface of the partition wall 31 j. An axis of the side guidemember support shaft 31 k coincides with a rotational center of a drivemember 35. A dislocation preventing projection 31 k 1 is formed at endportion of the side guide member support shaft 31 k so as to projectdownwards (refer to FIG. 4). A side guide member 34 is loosely fitted onthe side guide member support shaft 31 k so as to rotate freely thereon.The side guide member 34 is prevented from being dislocated by thedislocation preventing projection 31 k 1. The side guide member 34 is anannular roller.

As shown in FIGS. 3 and 4, the head rotational shafts 31 a, 31 b areformed on left and right side surface portions of the head main body 31,respectively, so as to be erected towards the left and right. These headrotational shafts 31 a, 31 b are brought into rotatable engagement withthe rotational support holes 32 b 1, 32 c 1, whereby the head main body31 is supported by the head support member 32 so as to rotate back andforth.

The head rotational shafts 31 a, 31 b are made up of substantiallycylindrical shaft portions 31 a 1, 31 b 1 and restricting projections 31a 2, 31 b 2. The restricting projections 31 a 2, 31 b 2 are each formedinto a trapezoidal shape when seen sideways that contacts the shaftportions 31 a 1, 31 b 1 along a bottom side thereof. The restrictingprojections 31 a 2, 31 b 2 are formed so as to project upwards andrearwards from outer circumferential surfaces of the shaft portions 31 a1, 31 b 1, respectively.

In bring the head rotational shafts 31 a, 31 b into engagement with thecorresponding rotational support holes 32 b 1, 32 c 1, specificallyspeaking, the shaft portions 31 a 1, 31 b 1 are supported rotatably bythe corresponding rotational shaft bearing portions 81 b, 81 c. Then,the restricting projections 31 a 2, 31 b 2 are brought into engagementwith the rotation restricting portions 82 b, 82 c. Namely, front andrear side surfaces of the restricting projections 31 a 2, 31 b 2 can bebrought into abutment with end faces of the corresponding sectorrotation restricting portions 82 b, 82 c.

FIGS. 6 and 7 illustrate states in which the front and rear surfaces ofthe restricting projections 31 a 2, 31 b 2 are brought into abutmentwith the end faces of the corresponding rotation restricting portions 82b, 82 c. For example, in the case of the state shown in FIG. 6, one sidesurfaces (front side surfaces) of the restricting projections 31 a 2, 31b 2 are brought into abutment with one end faces (front end faces) ofthe rotation restricting portions 82 b, 82 c. In the case of the stateshown in FIG. 7, the other side surfaces (rear side surfaces) of therestricting projections 31 a 2, 31 b 2 are brought into abutment withthe other end faces (rear end faces) of the rotation restrictingportions 82 b, 82 c. In this way, the case main body 5 to which the headsupport member 32 is connected via the head unit support member 20 canrotate relative to the transfer receiving surface S in an angular rangeof about 30 degrees to 90 degrees.

When looking at the head unit 30 sideways as shown in FIGS. 6 and 7, arotation center Q about which the head rotational shafts 31 a, 31 b aresupported rotatably in the rotational support holes 32 b 1, 32 c 1 ispositioned closer to the transfer projecting portion 31 b than a middlepoint in the front-to-rear direction between a contact point P where alower end of the transfer projecting portion 31 g is brought intoabutment with the rear surface of the transfer tape T to press againstthe transfer tape T and a rotational center C of the drive member 35.

On the other hand, as shown in FIG. 8A, the tape feeding member 33includes a drive shaft 33 a. The drive shaft 33 a is made up of the mainshaft 33 a 1 and the end portion shaft 33 a 2. The main shaft 33 a 1 andthe end portion shaft 33 a 2 are coaxial. An outside diameter of themain shaft 33 a 1 is formed greater than an outside diameter of the endportion shaft 33 a 2. The annular drive member 35, which is a roller, isfixed to a left end of the main shaft 33 a 1. A substantiallycylindrical drive wheel 35 a is provided on the drive member 35. Acircumferential groove 35 a 1 is formed in the drive wheel 35 a, and adrive wheel 35 b is fitted in the groove 35 a 1. This drive wheel 35 bis formed of a silicone material and is brought into contact with thetransfer receiving surface such as a surface of a sheet of paper. Thedrive wheel 35 b has an annular shape.

A protuberant portion 36 is provided at a right end of the main shaft 33a 1, and this protuberant portion 36 protrudes into an annular shapefrom the drive shaft 33 a. A substantially cylindrical protuberantportion wheel 36 a is provided on the protuberant portion 36. Acircumferential groove 36 a 1 is formed in the protuberant wheel 36 a. Asurface of a bottom portion of the groove 36 a 1 is formed so as toslope downwards to the left or to open towards the right. As shown inFIG. 8A, an open angle of the surface of the bottom portion of thegroove 36 a 1 relative to an axis L of the drive shaft 33 a is expressedby an angle α.

Further, a feeding roller 36 b is fitted in the groove 36 a 1, and thisfeeding roller 36 b is made of a silicone material and is brought intothe rear surface of the transfer tape T. An outer circumferentialsurface of the feeding roller 36 b is also formed so as to slopedownwards to the left or to open towards the right. In other words, thefeeding roller 36 b of the protuberant portion 36 that is brought intoabutment with the transfer tape T is formed into a truncated cone shapewhose upper surface is oriented to the left. Here, the surface of thebottom portion of the groove 36 a 1 and the outer circumferentialsurface of the feeding roller 36 b are formed parallel. Consequently, anopen angle of the outer circumferential surface of the feeding roller 36b relative to the axis L becomes the angle α. Then, an outside diameterD1 of the drive wheel 35 b of the drive member 35 and an outsidediameter D2 of an upper surface side of the feeding roller 36 b that isformed into the truncated cone shape substantially coincide with eachother.

As shown in FIG. 5, the tape feeding member 33 that is formed in the waydescribed above is supported rotatably by the support portion 31 h ofthe head main body 31 while being inclined so that the upper surfaceside of the protuberant portion 36 that is formed into the truncatedcone shape is positioned lower. Then, an angle that is formed by theaxis L of the drive shaft 33 a of the tape feeding member 33 that issupported while being inclined and the transfer receiving surface S suchas a surface of a sheet of paper is set to the angle α. Then, a lowerend edge (in other words, an abutment portion with the rear surface ofthe transfer tape T) of the feeding roller 36 b of the protuberantportion 36 that opens at the angle α relative to the axis L becomessubstantially parallel to the transfer receiving surface S. Further,while the drive member 35 is brought into contact with the transferreceiving surface S, the feeding roller 36 b of the protuberant portion36 is disposed so as to be spaced apart from the transfer receivingsurface S.

An outside diameter of the side guide member 34 that is provided so asto face the drive wheel 35 b of the drive member 35 substantiallycoincides with the outside diameter D1 of the drive wheel 35 b (refer toFIG. 8A). Then, the transfer tape T is positioned between the side guidemember 34 and the drive member 35. The side guide member 34 and thedrive member 35 are disposed so that their inner surfaces lie near sideedges of the transfer tape T. Consequently, the transfer tape T isguided by the side guide member 34 and the drive member 35.

In this way, the side guide member 34 and the drive member 35 make upside rollers that rotate back and forth while being in abutment with thetransfer receiving surface S to thereby enhance the capability oftraveling straight of the head main body 31 when the head main body 31is caused to travel to the rear. Namely, the side rollers are disposedat two locations lying outwards of both the side edges of the transfertape T as the side guide member 34 and the drive member 35. Then, thesupport shafts of the side rollers, that is, the side guide membersupport shaft 31 k that supports the side guide member 34 rotatably andthe drive shaft 33 a to which the drive member 35 is fixed are providedso as to be spaced apart from the transfer tape T.

Next, the operation of the film transfer tool 10 in the transferoperation will be described. As shown in FIG. 6, when the film transfertool 10 is pulled backwards, the transfer tape T is fed out towards thetransfer projecting portion 31 g by the feeding roller 36 b of theprotuberant portion 36 that is brought into abutment with the transfertape T from the rear surface thereof. At the same time as this operationis performed, the transfer tape T is pressed against the transferreceiving surface S by the transfer projecting portion 31 g, whereby atransfer layer that is provided on a front surface of the transfer tapeT is transferred on to the transfer receiving surface S.

As this occurs, the film transfer tool 10 is caused to travel straightbackwards in a stable fashion by the side guide member 34 and the drivemember 35 that constitute the side rollers. In addition, a lightpull-back feeling can be realized because the transfer tape T is fed outtowards the transfer projecting portion 31 g by the feeding roller 36.Further, the transfer layer of the transfer tape T is transferred on tothe transfer receiving surface in an ensured fashion.

A outer circumferential speed of the drive wheel 35 b and an outercircumferential speed of the feeding roller 36 substantially coincidewith each other because the outside diameter D1 (refer to FIG. 8A) ofthe drive wheel 35 b and the outside diameter D2 (refer to FIG. 8A) ofthe upper surface side of the feeding roller 36 b that is formed intothe truncated cone shape substantially coincide with each other. On theother hand, a speed at which the transfer tape T is fed (hereinafter,referred to as a “feeding speed”) substantially coincides with the outercircumferential speed of the drive wheel 35 b that rotates while kept incontact with the transfer receiving surface S. Consequently, the feedingroller 36 b can feed the transfer tape T towards the transfer projectingportion 31 g in an ensured fashion because the outer circumferentialspeed of the feeding roller 36 b and the feeding speed of the transfertape T substantially coincide with each other.

In FIG. 5, the drive wheel 35 b is in contact with the transferreceiving surface S while being inclined. However, the drive wheel 35 bis formed from a soft silicone material, and therefore, the drive wheel35 b rotates while kept in substantially parallel abutment with thetransfer receiving surface S.

The transfer tape T whose transfer layer is transferred at the transferprojecting portion 31 g travels upwards on the front surface 31 g 2 ofthe transfer projecting portion 31 g, continues to travel over thecurved surface 31 c while being guided by the guide projections 31 d, 31e and is finally taken up into the interior of the case main body 5. Asthis occurs, a connecting portion between the front surface of thetransfer projecting portion 31 g and the curved surface 31 c is formedcontinuously, and therefore, the transfer tape T from which the transferlayer has been transferred can be taken up smoothly.

In addition, the head main body 31 is supported rotatably relative tothe head support member 32. Consequently, as shown in FIG. 6, thetransfer operation can be carried out with the case main body 5 keptlying substantially flat or horizontal relative to the transferreceiving surface S. Alternatively, as shown in FIG. 7, the transferoperation can also be carried out with the case main body 5 kept lyingerected or vertical relative to the transfer receiving surface S.

As this occurs, the rotational center Q of the head rotation shafts 31a, 31 b that are supported in the rotational support holes 32 b 1, 32 c1, respectively, is positioned closer to the transfer projecting portion31 g than the middle point C between the contact point P of the transferprojecting portion 31 g and the rotational center C of the drive member35. Thus, even though the case main body 5 is disposed at any anglerelative to the head main body 31 (that is, either in the case shown inFIG. 6 or in the case shown in FIG. 7), the pressing force transmittedfrom the case main body 5 is exerted more on the transfer projectingportion 31 g than on the drive member 35 (and the side guide member 34).Consequently, even though the case main body 5 is kept traveling on thetransfer receiving surface S at any angle, it is possible to reduce therisk of a bonding failure of the transfer layer that would otherwise becaused due to insufficient pressing force being exerted on the transferprojecting portion 31 g.

Next, modified examples made to the tape feeding member 33 will bedescribed based on FIGS. 8B to 8D. Like reference numerals will be givento like members or portions to those of the tape feeding member 33 shownin FIG. 8A, and the description thereof will be omitted or simplified.In a tape feeding member 133 shown in FIG. 8B, the protuberant portion36 of the tape feeding member 33 shown in FIG. 8A is modified, and anannular protuberant portion 136 is provided in which an edge portion ischamfered to be rounded and which is formed of a soft material such as asilicone material or a thermoplastic elastomer. The protuberant portion136 is fixed to a drive shaft 33 a through bonding or two-colorextrusion. An outside diameter of the protuberant portion 136substantially coincides with an outside diameter of a drive member 35.

In a tape feeding member 233 shown in FIG. 8C, the protuberant portion36 of the tape feeding member 33 shown in FIG. 8A is modified, and anannular protuberant portion 236 is provided which is formed into apolygonal shape when seen sideways. This protuberant portion 236 is alsoformed of a soft material such as a silicone material or a thermoplasticelastomer and is fixed to a drive shaft 33 a through bonding ortwo-color extrusion. An outside diameter of this protuberant portion 236substantially coincides with an outside diameter of a drive member 35.

In the tape feeding member 233 shown in FIG. 8C, a guide roller 238 thatguides the transfer tape T is provided so as to be fixed on to a driveshaft 33 a between the drive member 35 and the protuberant portion 236.In this way, the member that guides the transfer tape T may be providedseparately from the drive member 35.

A tape feeding member 333 shown in FIG. 8D can be provided on the headmain body in place of the tape feeding member 33 shown in FIG. 8A andthe side guide member 34 (refer to FIG. 5). The tape feeding member 333includes a drive shaft 333 a. The drive shaft 333 a is made up of a mainshaft 333 a 1 and an end portion shaft 333 a 2. The main shaft 333 a 1has an outside diameter that is greater than that of the end portionshaft 333 a 2. A drive member 35 is provided fixedly at a left end ofthe main shaft 333 a 1. On the other hand, a protuberant portion 336 isformed at a right end portion of the main shaft 333 a 1 where the mainshaft 333 a 1 is connected to the end portion shaft 333 a 2. Thisprotuberant portion 336 is also formed from a soft material and isprovided fixedly on the drive shaft 333 a.

The protuberant portion 336 is formed into a truncated cone shape. Then,a diameter of the protuberant portion 336 that corresponds to an uppersurface of the truncated cone shape coincides with that of a drive wheel35 b. Additionally, an angle at which the protuberant portion 336 isopened to the right relative to an axis L of the drive shaft 333 a isset to an angle α.

Further, a side guide member 334 is provided on the end portion shaft333 a. The side guide member 334 is formed into an annular shape and isloosely fitted on the end portion shaft 333 a 2. Namely, a rotationalforce is not transmitted from the drive shaft 333 a to the side guidemember 334. A diameter of the side guide member 334 is formed greaterthan that of the drive wheel 35 b.

The tape feeding member 333 that is configured in the way describedabove is provided rotatably on the head main body in such a way that theside guide member 334 and the drive wheel 35 b are brought into contactwith the transfer receiving surface S. Here, an outside diameter of theside guide member 334 is greater than an outside diameter of the drivewheel 35 b. Consequently, the drive shaft 333 a is provided on the headmain body in such a way as to be inclined so that a side guide member334 side (that is, a right side) of the drive shaft 333 a is positionedhigher. As this occurs, the transfer tape T located where theprotuberant portion 336 is provided is not in contact with the transferreceiving surface S. In other words, the protuberant portion 336 isspaced apart from the transfer receiving portion 336. In thisembodiment, the angle at which the axis L of the drive shaft 333 a isinclined relative to the transfer receiving surface S is set to theangle α. Thus, a lower end edge of the protuberant portion 336 when seenfrom the front becomes parallel to the transfer receiving surface S.Namely, the protuberant portion 336 is brought into parallel abutmentwith the rear surface of the transfer tape T.

In this way, as shown in FIGS. 8A to 8D, the protuberant portion that isformed so as to protrude from the drive shaft can take the variousshapes. Then, the protuberant portion is brought into abutment with partof the rear surface of the transfer tape T by being formed so as toprotrude from the drive shaft. Consequently, compared with a case wherethe protuberant portion is formed to extend over the width of thetransfer tape T, a surface contact pressure at the abutment portion canbe increased higher, whereby the transfer tape T can be fed towards thetransfer projecting portion 31 g in a more ensured fashion.

Thus, while the embodiment of the invention has been describedheretofore, the invention is not limited to the embodiment but can becarried out in various forms. For example, the drive member that drivesthe drive shaft rotationally as a result of being brought into contactwith the transfer receiving surface S can be configured as a tapefeeding member that is separate from the drive shaft on which theprotuberant portion is provided. As this occurs, a transmissionmechanism is provided which transmits the rotational force of the drivemember to the drive shaft on which the protuberant portion is provided.

In this embodiment, the transfer projecting portion 31 g is disposed atthe front side, and the tape feeding member 33 is disposed at the rearside of the head main body 31. However, the transfer projecting portion31 g and the tape feeding member 33 can be disposed the other way round.Namely, the tape feeding member 33 can be disposed at the front side andthe transfer projecting portion 31 g can be disposed at the rear side ofthe head main body 31. As this occurs, the used portion of the transfertape T is pulled to be fed into the case main body 5 by the tape feedingmember.

The mounting position of the side guide member 34 in the front-to-reardirection is not limited to the mounting position described in theembodiment. However, in order to obtain the capability of travelingstraight of the film transfer tool 10 in a more stable fashion, it ispreferable that the side guide member 34 is provided in a position thatfaces the drive member 35.

The side rollers of this embodiment are made up of the side guide member34 and the drive member 35 and are disposed individually near the sideedges of the transfer tape T. However, the invention is not limitedthereto, and hence, it is possible that the side rollers are disposed sooutwards of the side edges of the transfer tape T that the side rollersare spaced sufficiently apart from the side edges of the transfer tapeT.

In addition, the tape feeding member 33 can be disposed parallel to thetransfer receiving surface S, so that the protuberant portion 36 can beformed into a protuberant portion whose outside diameter is smaller thanthose of the drive member 35 and the side guide member 34.

In the embodiment, the transfer projecting portion 31 g is formed intothe triangular shape when seen sideways. However, the invention is notlimited thereto, and hence, various shapes can be adopted which includesa spatulate portion whose distal end is formed into a thin plate-likeshape.

In this embodiment, the head rotational shafts 31 a, 31 b are providedon the head main body 31 and are allowed to be brought into engagementwith the rotational support holes 32 b 1, 32 c 1 in the head supportmember 32 so that the head main body 31 rotates back and forth. However,the positional relationship between the shafts and the holes may bereversed.

The embodiment that has been described heretofore is presented as theexample of the invention, and there is no intention to limit the scopeof the invention. This novel embodiment can be carried out in othervarious forms, and hence, various omissions, replacements and/ormodifications can be made thereto without departing from the spirit andscope of the invention. The resulting embodiments and theirmodifications are included in the spirit and scope of the invention, aswell as in the scope of inventions described in claims and equivalentsthereof.
